Description

  • Design, build, and maintain AWS Lambda services in Node.js and Python for the serverless portfolio.
  • Lead AWS ADOT-based instrumentation for Lambda workloads, including OpenTelemetry layer adoption, configuration, OTLP settings, and runtime compatibility validation.
  • Develop GitHub Actions pipelines to standardize CDK Lambda constructs, reusable layers, environment variables, active tracing, Lambda Insights, and centralized log configuration.

  • Enforce observability practices for AWS cloud workloads, including PII-safe structured logging.
  • Build and maintain CI/CD pipelines for linting, unit tests, coverage, deployment, and post-deployment telemetry validation.
  • Create automated tests that verify tracing, logging, metrics, cold-start visibility, and alert behavior in Dynatrace and Splunk.
  • Develop Python-based solutions to capture Lambda errors, duration, throttles, retries, cold starts, workflow failures, and downstream latency.
  • Tune Lambda memory, timeout, concurrency, packaging, and network settings to balance observability overhead, reliability, and cost.

  • Strong analytical and problem-solving skills.
  • Preferred experience supporting VA or federal government IT systems, AWS services such as Lambda and API Gateway, Salesforce-based applications, enterprise API integrations, and systems that process sensitive or regulated data.
